How gravity belt thickening works. Gravity belt thickening (GBT) increases the sludge solids concentration (i.e. thickens the sludge) by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a moving belt) on which the sludge sits.. There are two types of belt-based processes for increasing sludge …

This can lead to thickening of the pleura, which narrows the pleural space and impairs lung function. Pleural thickening can give rise to chest pain, breathlessness, and other symptoms. Pleural thickening also often occurs in patients who have Mesothelioma, a rare and aggressive cancer of the pleura. [2]
